It took me all study hall to chew up all the paper
17 sheets in all from the math book of my neighbor

Greatest spitball in the world...

Justin gave me a nasty look just one time and then I took
The spitball out and launched it at his head

Justin, he was too quick, ducked and foiled my nasty trick
Splattered behind him on the wall, thus ends "The Great Spitball"
